Rewinding Machine safety operation guide -
First, prepare for work after taking over:
1. It is necessary to arrive at the post, check, and original record 15 minutes earlier. Comprehensive understanding of the above
The operation of a class of equipment, the quality of rewinding and safety.
2. Understand whether the previous class of paper is good; whether the class changes specifications, the weight and change
time. Check if the shift is cleared in the previous shift.
3, the middle and night shift rewinders must check whether the rewinding paper core tube and packaging materials are adequate.
4,Report the handover to the squad leader
Rewinding Machine operating procedures -
First, the boot process:
1. Turn on the total power of the rewinder and the power of the detection system in turn; Note: (1) Before turning on the power, please make sure that the circuit is connected correctly and there is no short circuit;
(2) When the main power is turned on, an alarm will occur. After about 5 seconds, after resetting through the touch screen, turn on the detection power.
2. Turn on the air source switch, please ensure that the air pressure is around 6Mpa;
3. According to the paper-feeding direction in the machine state of the touch screen, the product is paper-punched; Note: (1) Please select the paper-feeding state before putting on paper;
(2) Ensure that the core is in the middle position of the inflation shaft, and the core is installed on the left and right gas rise shaft
The same location;
Rewinder mechanical structure and control process ---
I. Overview of the double-roller under the paper rewinding machine
The mechanical structure of the lower paper rewinding machine is shown in Figure 2-1. It can be seen from the mechanical structure diagram of the rewinding machine that the lower paper rewinding machine is fed into the paper web from below the rewinding machine. The paper web is wound around a support roll and then rolled up with a roll of paper. The paper is ejected from the unwinding roll, passed through the lower transfer roll, and then the web passes through the slitting mechanism at a fixed position, bypassing the front backup roll (press The second roller in the direction of the paper line or the back support roller is then wound on the take-up reel.
During the rewinding process, the paper web passes through the eject roller, and the tension force formed by the paper web pulls the paper roll toward the support roller, and the tension of the paper roll is stabilized by the action of the tension, and the rewinding machine can be made at a high speed roll. The quality of the paper roll can be guaranteed when taken. The lower thread rewinding machine can also control the pressure between the platen roller and the paper roll by changing the transmission torque difference of the two supporting rollers, so that the pressure of the finished paper roll can be controlled, and the quality of the paper roll can be Do a good job of control.
It can be seen from the figure that since the slitting mechanism of the lower threader rewinding machine is installed at a fixed position, this can avoid axial sway during the rewinding process, and also facilitates the control of the winding of the paper roll. The role of most of these rewinders in the Middle East is not very high, very close to the ground, the center of gravity, relatively low, due to the lower center of gravity, the rewinder can remain stable at high speeds, so this Types of rewinding machines are widely used, and most of the paper mills in China use the lower thread rewinding machine. Through many practices, this rewinding machine is also the best performance. And its speed can reach 2,500 meters per minute, the width is also long, can reach 10 meters, can handle the rewinding of different types of paper, from low basis to cardboard can be re-rolled. Of course, it also has its own shortcomings. The disadvantage is that because it is close to the ground, it is not easy for the operator to access the bottom of the machine. It is also difficult to guide the paper. Therefore, when the mechanical equipment is installed, a pit will be placed under the machine. In order to make the operator more accessible, the high-grade rewinding adopts the automatic threading structure, and there is no such problem.
